Lights Out and Lights Dim Modes
Adobe is trying to make the photo editing process easier and more intuitive. One of the ways they’re doing this is by emphasizing the photo itself and making it easier for you to see exactly what you want. Lights Dim mode and Lights Out mode let you dim or get rid of all of the panels and extras, viewing just your image against a black background. Just press L to switch modes. The first mode, Lights Dim, is my favorite because you can still see your panels but they’re not "in your face," if you know what I mean (see Figure 5). What’s cool about this mode is that you can still edit the settings even though they’re somewhat hidden. If you press L again, you’ll go to Lights Out mode, where everything is hidden except the photo (see Figure 6). Just press L again to get back to the regular view.
Figure 5 Lights Dim dims the panels but still shows them in the background.
Figure 6 Lights Out hides the panels altogether.
